MODEL
FXDA
Fixed orifice, pressure compensated flow control valve
SERIES 2 / CAPACITY: 45 L/min. / CAVITY: T-5A
Fixed-orifice, pressure-compensated flow controls provide precise flow regulation for meter-in or meter-out
applications where there may be wide pressure fluctuations. The flow setting is specified by the user and is set at
the factory.

TECHNICAL FEATURES
Customer must specify a flow rating. Factory set flow ratings are within +/- 10% of the requested setting.
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage
the seals.
All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge
extension dimensions from the mounting surface may vary.
The sharp-edged orifice design minimizes flow variations due to viscosity changes.
The tuneable control option provides +/- 25% variation from the nominal factory pre-set flow. Turn the adjustment clockwise to increase.
Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel
components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of
Construction page located under TECH RESOURCES.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
